I'm just finishing my new shop and needed these to finishing installing my dust collection. They are good quality and they do the job. Fit is good with other product lines. Thanks

Be aware that dust collection sizes are not universal. These are meant to fit malleable dust collection hoses - not necessarily hard plastic fittings of the same size. My table saw has a 4" port and this product has a 4" port - guess what? They don't fit as they're exactly the same. Easy fix with epoxy and black duct tape. However the 2.5" port fit perfectly with my 2.5" Ridgid shop vac hose with no adjustment whatsoever.
